Long before the dawn of modern parenting, animals laid eggs and moved on, leaving their progeny to fend for themselves. Now, a study published in Nature uncovers one of the elegant ways evolution transformed neglect into nurture. Working with clonal raider ants, a surprisingly parental insect, researchers found that rather than evolving entirely new brain circuits for caregiving, evolution repurposed ancient neural systems for regulating hunger into triggers for social behaviors.

Wildflowers don't last long in the desert. If you want to catch those ethereal blooms before they wither in the heat, you have to get there fast. Say, in something like the Mercedes-AMG GT63 Pro. With 603 horsepower and 627 pound-feet of torque, plus all-wheel drive to keep you stable on sand-swept roads, the GT Pro can eat up desert highway quicker than the native sphinx moth caterpillars devour evening primrose.
Design is my favorite aspect of the automotive world. As a little kid it was how they looked that got me into cars, which led to me pursuing a degree in car design. Since I decided to become a writer instead, design is still the thing I love to talk about the most. Interviewing actual designers is my favorite part of the job, and styling is one of my main considerations when reviewing a new car.

When Dolly the sheep—the first cloned mammal—was born 30 years ago, she became one of the most famous animals in science history. Her arrival sparked predictions of a sci-fi future filled with cloned pets, cloned humans and even resurrected extinct animals like the wooly mammoth. But the reality of cloning has turned out to be much more complicated.
